The best line I've ever read (over at FG) between these two goes like this:
DLE is for the masses;
DA is for the classes.
Sums up everything between these two brands in a nice little poem.

Personally I'd go for the DLE-170. DA 170 is also another option. Most use tuned pipes on the 150 to match, but wow that's $$$ in the end for nearly the same thing! If you have money to burn, put pipes on the DLE-170 instead!

That is why I do go over to the DA clique boy forum.
